METHOD OF PROCESSING OXALATE MOTHER WATERS AND PULP WASTES CONTAINING TRANSURANIUM ELEMENTS Russian patent published in 2013 - IPC G21F9/04 G21F9/28

Abstract RU 2474898 C1

FIELD: process engineering.

SUBSTANCE: invention relates to treatment of radioactive fluid and pulpy wastes formed in recovery of radiated nuclear fuel. Proposed method comprises destructing oxalate ions in mother waters by nitric acid in the presence of variable-valency metal ions. Processing of oxalate mother solution and pulpy wastes comprises mixing mother solution with solid phase of hydroxide pulp.

EFFECT: power savings, decreased amount of radioactive wastes.
